Orientations

The basic ways of defining an orientation are:

• Orientation attribute plus optional WRT. For example:

  ORI OF /BOX1 WRT /*

• Cartesian orientation. For example:

  dir IS dir AND dir IS dir

• For example to set an orientation of an element to that of a section, rotated by 90 degrees use:

  (E IS U WRT /SCTN1 AND N IS E WRT /SCTN1)

• The AXES keyword, which will allow you to use P-points to specify orientations.

Syntax

Example

( AXES PLEAVE IS AXES PLEAVE OF PREV AND AXES P3 IS UP )

• This will orient a branch component, such as a valve, so that it is aligned with the previous component and its P3 is up.
